I'm not a fan of stainless brushes...too aggressive in my view.If you try to go only partially thru the bore you will multiply the effect at the point of reversal as the bristles try to reverse direction.At the least you ruin the brush at the worst you ruin the barrel.Push thru & remove the brush, repeat as needed.

Haemmerli supply stainless steel 32 brushes with the 280 pistol. The 280 barrels are surface hardened and the stainless will not harm them.

They, stainless brushes, remove Lead quickly. It worked so well, I clean my wife's Walther with it. Now I have a "Multi-groove" barrel. No worries, I know a guy that machined a replacement barrel for her.

If your friend is asking in reference to a .22, I constantly hear from .22 competitors to never use any kind of brush in a .22 bore. For .22, I personally use the VFG weapons care system pellets (you can find them on Brownells) and a Patchworm. For center fire, I use the VFG fiber pellets on a carbon fiber rod.

Totally agree with you Dave, I use the all copper Choreboy, and what really works good on the match barrel is bronze wool I bought at walmart. I wonder how that Freemont stuff works, you see it at gun shows now and again. It looks like stainless steel but is something softer like monel? Stan

The usual technique is to unravel some of the copper strip and then wrap that around an old bronze brush. May need to use side cutters to get the chore boy to unravel.

For lead, I've used an Outers foul-out for several years. Now that they're discontinued and you can't get the solution, I've started using Kroil. Never had to use anything more aggressive than a bronze brush.
